Následně byla zvýšena na 240 °C a za vakua oddestilován přebytek Bylo změřeno OH číslo polyesteru a přídavkem teplota neopentylglykolu neopenty1g1uko1u bylo OH číslo nastaveno na 24.DETAILED DESCRIPTION OF THE INVENTION The table of said aromatic aliphatic dicarboxylic acid and dihydroxy compound was added together with tetrabutyl orthothioate (TBOT) (added as 10 toluene) in the amounts also shown in Table 1 to Four-necked flasks and heated to 170-190 ° C and reacted at this temperature for 3-4 hours. The OH number of the polyester was measured and the OH number was set to 24 by adding the neopentyl glycol temperature of the neopentyl glycol.
